In the kinematic regime of turbulent dynamo with a negligible back reaction of magnetic fields,
the dynamo theory was developed by
[1]}
(see also [2]}, [3]}, [4]}).
When the magnetic back reaction becomes significant, we need to deal with the nonlinear turbulent dynamo.
Nonlinear turbulent dynamo is characterized by the energy equipartition between turbulence and magnetic fields
within the inertial range of turbulence.
